Class 7(5) [Also in Group XXXV] In an engine starter comprising a pinion 19 arranged to be coupled with the driving shaft of the starter motor and to be shifted axially into mesh with an engine gear 31, an electromagnet 4, 6 disposed at the end of the motor remote from the pinion and causing, when actuated, a bridge '8 to move in a direction towards the pinion, contacts 9, 14 and 9, 15 actuated by the bridge and arranged so that when the latter moves through a first distance the motor is energized via a resistance 18 and rotates at a low speed, and that when the bridge completes its movement the resistance is short-circuited, thrust rods 27 are provided which extend parallel to the motor shaft and bear at one end against the bridge 8 whilst the other ends are connected to an actuating ring which shifts the pinion towards the gear 31 when the bridge moves through the first distance. The bridge 8 is formed with opposed slots of different lengths in which is disposed a plate 10 carrying the ring contact 9. the unequal slot lengths causing the contact 9 to tilt when the electromagnet is energized and connect the motor to a battery via the contact 14 and the resistance, the resistance being cut out when the stroke of the electromagnet armature 6 is completed and the contact 9 is moved to a perpendicular position to engage contact 15. The first movement of the bridge causes the pinion to partially engage the gear 31 but upon completion of the stroke of the armature 6 the motor overruns the gear 31, and a dog 22, which is operationally connected to the pinion sleeve 19a, engages in a helical slot in a driving member 21 fixed to the motor shaft and effects complete engagement of the pinion in the gear 31. The actuating ring is provided with resilient buffers, which during the initial engaging movement, contact an element 24 attached to the pinion 19. When the engine overruns the starter the pinion 19 is retracted by spring 25 and the .element and buffers again abut and fractionally prevent overspeeding of the motor

Abstract: 301,507. Soc. Anon. des Procedes R. Audubert (S.A.P.R.A.). Dec. 2, 1927, [Convention date]. Capillary filters.-Fibres are woven into sheets, as for wicks, and the sheets are arranged back to back to form a pack. Such a pack may be placed in a rectangular box, Fig. 1, the sheets projecting slightly at the lower end. The strands in contact with the walls of the box are cemented by means of glue, gum, lacs, copal, cellulose varnish, polymerized phenols, or boiled oil. The element so formed is immersed in the liquid to be filtered and the filtrate is drawn away under slight suction through an outlet connected near to the top of the box. As shown in Fig 2, the sheets are compressed between side plates clamped over one or more perforated collector pipes, which pass through the upper portions of the sheets. The top and lateral edges of the sheets are rendered impermeable by cement as mentioned above. A filtering element may be built up of sheets with intermediate frames of the form shown in Fig. 3. The sides of these frames may taper inwards. Fig. 6 shows an element formed by winding a sheet around a tube 1 and held under compression by a stuffing box 4. The liquid, supplied by a pipe 7, enters the casing through apertures 8. The filtrate passes through apertures 6 into the outlet tube 1. A heating coil 9 may be provided. In each form of apparatus other filtering materials, such as un-sized paper, may be introduced between the woven sheets.

Filed: 1970-07-21
Abstract: 1312297 Change-speed control NISSAN MOTOR CO Ltd 21 July 1970 [22 July 1969] 35218/70 Heading F2D A governor for producing a fluid-pressure proportional to speed, for control of an automatic transmission on a motor vehicle, comprises a V-shaped body 22 mounted radially over the transmission output shaft 10 and housing diametrically opposite primary and secondary valve spools 42, 62, spring-loaded radially outwards and inwards respectively, governor output pressure 20 being zero below a predetermined speed on acceleration, and below a predetermined lower speed on deceleration. In Figs. 1 and 2, at standstill, input pressure 18 initially passes the small outer land 44 of the primary valve-spool 42, and through a crossover passage 56 to the secondary valve, where it is blocked by the large outer land 66. At a predetermined speed of the shaft 10, the secondary valve spool 62 moves centrifugally outwards against spring load 68 and supplies governor pressure to the outlet 20 at a pressure which increases with speed by the regulating action of both valves. On deceleration, the secondary valve-spool 62 closes at lower speed than its opening speed, due to delivery pressure acting outwards on its larger outer land, thereby providing hysteresis. In Figs 4 and 5 (not shown), the direction of flow is reversed, the feed being to the secondary valve which is moved outwards by supply pressure to open the feed to the cross-over passage. In this case therefore the speed at which the secondary valve opens to commence delivering governor pressure varies with the pressure of the supply. As shown in Fig. 1, the centre-line p of the valves is displaced from the shaft diameter r.
